? The LIN master requests a SoftStop .
? The SoftStop will correspond to the following two
data bytes LIN writing frame (type #1).
SoftStop
If a SoftStop command occurs during a motion of the stepper motor, it provokes an immediate deceleration to Vmin (see
Minimum Velocity) followed by a stop, regardless of the position reached. Once the motor is stopped, TagPos register is
overwritten with value in ActPos register to ensure keeping the stop position.
Note : The dynamic ID allocation has to be assigned to
‘General Purpose 2 Data bytes’ ROM pointer ‘0000’. The
command is decoded only from the command data.
Note : A SoftStop command occurring during a
DualPosition sequence is not taken into account.
Command SoftStop occurs in the following cases:
? The chip temperature rises above the thermal shutdown
threshold (see DC Parameters and Temperature
Management);
